OSCAR MCCULLOUGH OF VINONA, MINNESOTA, ASSIGNOR TO C. F. SCI'IROTI'I, OFSAME PLACE.

TENONlNG-MACHINE.

SEECIFIGATIOII forming part of Letters Patent N 0. 408,352, dated August6, 1889.

Application filed March 29, 1888. Serial No. 268,730. (No model.)

To all whom it may concern:

Be it known that l, OSCAR MCCULLOUGH, a citizen of the United States,residing at WVinona, in the county of \Vinona and State of Minnesota,have invented certain new and useful Improvements in Tenoning-Nlachines;and I do declare the following to be a full, clear, and exactdescription of the invention, such as will enable others skilled in theart to to which it appertains to make and use the same.

This invention relates to improved attachments, which are applicable toeither the wellknown wood-frame or to the metal-frame ten- I 5oning-machinesuch as shown, for instance, in Patent No. 115,603, datedJune 6, 1871.

The objects of the improvements or attachments are, first, to enable theoperator to form sash-bar tenons for check or lip rail sasl1,which 2odifler at the shoulders, without a resetting of the tenoning machine, asheretofore required, and to finish each bar at one operation,'and,second, to finish so-called sash-muntins by cutting the tenon the eXactrequired length after being formed and at one operation.

The improved attachment will be fully understood from the followingdescription, when taken in connection with the annexed drawings, inwhich Figure 1 is an elevation of a tenoning-machine with a woodenframe, showing my improvements attached thereto, and as shown enlargedin Figs. 3, 4, and 5. Fig. 2 is a similar View of a tenoning-machinewith a metal frame, showing the same improvement attached. Fig. is a topor plan view of the attachment. Fig. a is a front elevation of the same.Fig. 5 is an elevation of one end of Fig. 4. Fig. 0 is a cross-sectionof a dado cutter-head to be used as a substitute at option for the sawsshown in Figs. 4, 5, and 7. Fig. '7 is a view of one side of a combinedcut ting and grooving device, shown by edge views in Figs. 3 and 1. Fig.8 is a detail plan View of one end of the bottom sash-bar after thetenon is formed, as usual, by the cutters of the tenoning-machine. Fig.9 is a detail plan view of the bar shown in Fig. 8 after passing throughthe attachment, the portion removed being shown in dotted lines. Fig. 10

is a detail plan view of one end of the top sash-bar after the usualtenon is formed, and

a portion at one side shown in dotted lines removed by the attachment.Fig. .11 is a detail plan view of one end of a finished muntin 5 5 withthe tenon cut to the proper length. Fig.

12 is a similar view of the muntin shown in Fig. 11 previous to theshortening of the tenon. Fig. 13 is a perspective View of atenoningmachine with my attachment applied, the va- 6o rious detailscommon to tenoning-machines being omitted.

In the annexed drawings, Fig. 1, I have represented the main parts of awood-frametenoning machine, and in Fig. 2 I have shown the main parts ofa met-al-frame-tenoning machine, constructed substantially as shown inthe patent before referred to.

In both machines I) Z) designate cutterheads; 0, a belt-tightener; a,the counter and 7c pulley; d, the cope-head; e, a vertical shaft;

f, a driver-belt pulley thereon, and g, a driverbelt pulley for theshaft of the cope-head (Z. These parts are old and well known, and forthis reason do not need a more full and clear description. The carriageupon which the wood is placed while the tenon is formed and upon whichit is carried until its final completion by my attachment is not shownin the annexed drawings, except in Fig. 13, where it is designated bythe letter 0, being common to all tenoning-machines and identical inprinciple, being arranged to move horizontally from left to right, andvice versa, as clearly shown in the patent before mentioned, so that thesash-bar first passes between the cutter-heads I) Z), which form thetenons s or 5, Figs. 8 and 10; then past the cope-head d,wh ich givesthe ogee form to the end of the side 8', Figs. 8 and 9, as usual, and.then, if necessary, over the 0 saws or cutter-head running on the lowerbracket or under the saws or cutter-head running on the upper bracket ofmy improved attachment, which I am now about to describe.

On the vertical shaft 6 are fastened two driving-belt pulleys G G,which, by means of belts suitably applied to pulleys D D, (shown in Fig.4,) are designed to give rotation to the arbors F F and the saws orcutter-heads thereon. I00

When my attachment (aside from the pulleys G G mentioned, andconsisting, primarily, of two double bracketarms B B or four singlearms, if preferred, carrying said arbors F F, journaled in boxes, asshown) is .to be affixed to metal-frame-tenoning machines or secured tothem by set-screws s s for endwise set and adjustment of these arbors.For effecting aproper vertical adjustment of the face-plate A and thebracket B, slotted boltholes are preferred.

On the ends of said arbors F F are rigidly secured, by flanges h andflanged nuts h,the

rotary cutters O O, which are adjustable laterally by means of collars EE, as shown,,and may respectively consist of a groove-saw t and aspur-saw t, as shown in Fig. 7. In lieu of these cutting devices 0 O, Imay substitute cutters of the form shown in Fig. 6 or of any otherdesired form.

In using the machine containing my im- 7 proved attachment the operatortakes a bar,

lays it on the carriage of the machine with the part 3 Fig. 8,uppermost, and, moving the carriage, presents one end of the bar to thecutter b, which forms the tenon s. The carriage is then moved to thecope or cutterhead d, which gives the ogee form to the end of the side8', as shown in Fig. 8.

Thus far the operation and production of the machine is as usual insash-makin g to form the end of the sash-bar to fit the upper sash-railof the upper sash. The bar is then reversed and the end treated in thesame manner. However, as the side 5 is too long to fit the lip orshoulder 011 the top sash-rail it has been usual to adjust one of thegutters b to out the said side shorter than the side 5. To obviate suchadjustment of the cutters b is the object of my attachment. The lowercutter 0 having been properly adjusted, the carriage is moved forwarduntil said cutter reduces the side .9 as shown in dotted lines, Fig. 9.The same procedure is then had with the bottom sash-bar. The saws orcutterheads on top arbor F having been adjusted laterally to place, byadjusting the collars E E the first tenon is made on the machine, asbefore, and illustrated in Fig. 8. The bar is then reversed, placedagainst a stop, (designated in Fig. 13 by C and the second tenon madeprecisely as the first, and, without stopping the operation, thecarriage is moved forward carrying the bar under and beyond the saws orcutter head 0, running on the upper bracket of the improved attachment.The bottom sash-bar is thus finished, as shown in Fig. 9. The tenon isshown at s", the reduced side at and the other side at 5 Further, inusing my attachment for forming tenons on sash-muntins the tenon isformed on the machine in the usual manner, passing the cutter andcope-heads of said machine, (illustrated in Fig. 12,) and withoutstopping operation the carriage holding the muntin stuff is movedforward and past the saws or cutterheads running on either upper orlower brackets of my attachment, thus cutting the tenon the exactrequired length and in the same operation. The finished end of themuntin isillustrated in Fig. 11.

Having described my invention, what I claim is 1. In a machine forforming sash-bar tenons for check or lip rail sash, the combination ofthe rotative cutters b b and rotative cutters O O, with the interposedcope-head (1, arranged in the relation described, and a reciprocatingcarriage adapted to support and guide the stuff, as specified.

2. In a machine for forming sash-bar tenons for check or lip rail sash,the combination of the rotative cutters b b, the rotative cutters C 0,having endwise-adjustable shafts, the verticallyadjustablebracket-bearings for said shafts, the cope-head (1, arranged asdescribed, and a reciprocating carriage adapted to support and guide thestuff, substantially as specified.

In testimony whereof I affix my signature in presence of two witnesses.

OSCAR MOCULLOUGH.
